AI Article Synopsis
- Several previous studies explored the -1304T > G polymorphism in the MKK4 gene's impact on cancer risk, but lacked sufficient subjects for strong conclusions.
- A comprehensive meta-analysis was conducted, analyzing data from 8 independent case-control studies involving 4623 cancer cases and 5256 controls to better assess this genetic factor.
- The findings suggest that the -1304T > G polymorphism may decrease cancer risk, but more extensive research is needed to confirm these results.
Article Abstract
A number of epidemiological studies have assessed the association of -1304T > G polymorphism in the MKK4 gene and risk of cancer, but the results lack of statistical power due to the limited subjects used in these studies. This study was devised to identify the genetic effects of the -1304T > G polymorphism on cancer risk in a large meta-analysis.Eligible studies were identified by searching both Chinese and English databases. General as well as subgroup analyses were performed for 8 independent case-control publications with a total of 4623 cases and 5256 cancer-free controls. Odds ratios (ORs) and 95% confidence intervals (CIs) were used to estimate the association.Overall, this meta-analysis showed that the association between the -1304T > G polymorphism and cancer risk was statistically significant (GG vs TT: OR = 0.63, 95% CI, 0.52-0.75; GG + TG vs TT: OR = 0.85, 95% CI, 0.79-0.91; GG vs TG + TT: OR = 0.67, 95% CI, 0.56-0.80; G vs T: OR = 0.82, 95% CI, 0.77-0.88; TG vs TT: OR = 0.86, 95% CI, 0.79-0.93).Our meta-analysis reveals that the presence of the -1304T > G polymorphism is likely to decrease risk of cancer. Future larger studies are necessary to validate the current finding.

Idiopathic clubfoot (IC) can be corrected initially using the Ponseti method, but still there is a high recurrence rate. The etiology of IC may include many undetermined genetic and environmental factors. Single nucleotide polymorphism of rs274503 in has been found to be associated with IC in Caucasian children.

Interleukin 1 receptor antagonist (IL1RN) is a competitive inhibitor of interleukin 1 (IL-1). Natural killer cells (NK cells) contribute to the elimination of viruses by their antiviral effector function, which depends on a balance between inhibitory and activating receptor genes such as NKG2D and NKG2A. Using polymerase chain reaction restriction fragment length polymorphism (PCR-RFLP) assays, the association of intronic single-nucleotide polymorphisms (SNPs) in these genes with viral infection were assessed in 111 patients with hepatitis E virus (HEV) infection and 222 HEV-naive healthy controls.
